Just connect the smartphone with the Wi-Fi network and you'll be able to contact your employees and coworkers over the mobile wireless company network. Sunrise offers this service with free delivery and no basic monthly fee.

Calls made over Wi-Fi, SMS, and MMS are charged at the regular Sunrise rates. You don't need to have Internet service with Sunrise to use it - but we would be even more excited if you were to take advantage of our entire package. According to test reports from Bilanz, we are ultimately the best universal provider for small and mid-sized companies in Switzerland.
